One of our undergraduate students, Kyle Murphy, (now a former student) has made a collection of folder containing many of the activities we have used at our Math Circle. There is also a spreadsheet with links to these activities. Students can access basic descriptions of our activities here. There is a second version of the folders with more information, including some solutions, a list of required materials and advice to the instructor. Instructors can obtain access to these additional resources by filling out this form.
If you have any questions about the form, please email us at <mathcircle@tamu.edu>.
If you use our materials, please let us know how it went.

TAMU Math Circle Apps
During the pandemic, Phil Yasskin and Carl Van Huyck developed a collection of online activities that work well for online math circles. Most of them are still useful. They can be accessed at TAMU Math Circle Apps .
In particular, one of the apps is the game Pop Tac Toe, developed by Phil Yasskin based on the game Berserker he played at an online Julia Robinson Festiival math circle. It can be played in-person using a checkerboard and either checkers or chess pawns. Or it can be played on Zoom with one person sharing their screen. It has become very popular among math circle students and undergraduate students at Texas A&M. Two of our undergraduate student, Lucian Chauvin and Mckinley Xie, programmed Stockfish (the world champion chess computer program) to play Pop Tac Toe and then Lucian and Carl made this available at the Math Circle website. You can adjust the difficulty, but it can be beaten. Good Luck!
